Our invention relates to improvements in centrifugal apparatus forcleaning, cooling, mixing or otherwisetreating gases, vapors,

' liquids and the like. 4 The invention concerns apparatus of the typein which the substance to be treated is subjected to the centrifugalaction of a rotor comprising discs mounted for rotation in a casing orhousing.

The principal object of our invention is to 1 increase the efficiencyofthis type of apparatus and We accomplish this object, primarily, bythe useof discs with surface projections or irregularities, asdistinguished from the use of plane discs or plates as heretofore. Byemploying discs with surface projections or irregularities, the frictionagainst the discs of the substance being treated is increased, thecentrifugal action of the discs is enhanced and greater pressure andconsequently increased advance of the gas and/or liquid through theapparatus are achieved. 7

The invention is illustrated in the accom- H panying drawings,.in whichFig. 1 is a trans- 1 verse section of a fragment of the completeapparatus; Fig. 2 is an elevation of a fragment of a disc having radialprojections; Fig. 3 is a similar View of a disc fragment in which theprojections are radially inclined; Fig. 1 is an edge View of a pluralityof discs in which the projections are formed by nuts and bolts; Fig. 5is an elevation of a frag ment of the disc of Fig. 4; Fig. 6 is an edgeview of a plurality of discs in which the projections are carried by thespacersbetween adjacent discs; Fig. 7 is an elevation of a fragment of adisc having winged projections. Fig. 8 is a view somewhat like Fig. 1

but in which the projections of the discs extend alternately at oppositefaces of the disc; Fig. 9 is an elevation of a fragment of a disc ofFig. 8 with the projections forwardly inclined; Fig. 10 is a similarview with the projections rearwardly inclined; Fig. 11 is a K similarview with the projections radial;

Fig. 12 is a fragmentary elevation of a modification in which a wheel isused in lieu of a disc with the projections in the spokes or arms of thewheel; Fig. 13 is an edge view of a series of discs like those of Fig.12; Fig. 14

is fragmentary elevation of a modified form of wheel in which the spokesor, arms are curved instead of being radial; Fig. 15 is a fragmentarycross section and Fig. 16 a fragmentaryelevation of a structurein whichaserles of flat rings with pro ections 1s used increase the efliciencyof the apparatus as a whole. 7

Referring tofFig. 1 of the drawings, 10 denotes the housing or casingwherein rotates a plate 11 which carries the discs denoted generally as12. The plate 11 is mounted on a rota'ryshaft 13 which, when it rotates,carlies the plate and discs around with it. Se-

cured approximately'centrally to the plate 111 is a perforateddistributing cone 14 to which the substance to be treated is suppliedusually under pressure, through the supply pipe or nozzle 15. The partsso far described are old and well known in the art and re quire nodetailed description.

In the operation of a device of this character, the substanceor mixtureto be treated, say gas andwashing liquid, is introduced through the pipe15 into the distributing cone 14L whence it passes to the discs 12which, by centrifugal action, bring about the desired result, whether itbe a mixing effect, a scrubbing or purifying of gases, the coolingthereof, etc.

The discs12 are secured to the plate 11 by rods or bars 16 and are heldsuitable distances apart thereon by the interposed spacers 17 In Fig. 2,the disc 12 has struck up radial projections 18 and in Fig. 3, the disc12 has struck up radially inclined projections 18 In Figs. e'and 5 thediscs 12 have projections in the form of nuts and bolts 18 of anydesired shape and preferably arranged so that the projections in onedisc are staggered with relation to r the projections of an adjacentdisc.

disc 12 and alternateprojections extend from opposite faces of the disc.In Fig. 8, 10 is the casing, 11 the disc supporting'plate and 13 theshaft upon which the plate is mounted. Each disc 12 has struck uptherefrom projections 18 and18 the former extending to the left of thedisc and the latter to the right thereof. It will be noted that theprojections on one side of one disc extend into the spaces betweentheproj ections on the opposed face of the adjacent disc. 'In Fig. 9 theprojections 18 and 18 are inclined forwardly or in the direction ofrotation of the disc, in Fig. 10 the projectionsare inclined rearwardlyor opposite the direction of rotation of the disc and in Fig. 11 theprojections are radial. or

In Figs. 12 to 14 wheels in lieu of discs are shown. The wheel 12 ofFig. 12 has radial projecting from the faces of the discs and each suchseries extending in a line from the hub to the perphery of a disc andconstituting a rib with numerous interruptions, and horizontal shaftsupporting and adapted to rotate all the discs within the casing.

3. In a centrifugal apparatus for the purpose specified, the combinationwith the elements claimed in claim 2, of spacing members fixedto thediscs between the same and carry ing said projections.

4. Ina centrifugalapparatus for-the purpose specified, the combinationwith a casing, of a rotor therein comprising. rotatable discs only saiddiscs spaced apart and having each a plurality of series of surfaceprojections each series of projections extending in a line from the hubto the periphery of thedis'c and constituting a rib wlth numerousprojections,

a horizontal rotatable shaft extending into said casing and meanssecuring each disc in the casing to said shaft whereby rotation of saidshaft effects rotation ofeach and'every disc in the casing. v

Except for the use of a wheel insteadof a disc, the construction is similar to that of Figs.'8 to 11. .InFig. H the arms 19 of the wheel 12 are curved, but in other respects theconstruction is analogous tothatof Figs. 12 and 13.

In Figs. 15 and 16 the rings 12 with proj ections l8 are shown, theserings being used in some cases in lieu of the'discs or wheels shown incertain of the other views of the numerous interruptions, theprojections on.v
